|Supramk3||Thanks guys!!! Glove box it is|

|Jvs1991||I just looked at my car and on the driver side firewall there's a area of the foam deadening material that is cut already. If you peel it back there's a black rubber square grommet that should be good.|

For my install, I mounted the fog light relay in the engine bay on near the drivers side, up close to where the hood pivots near the windshield. It's almost hidden. I ran the wires along the very top of the firewall over to the passenger side and then down to that large grommet. I also installed a switch in line so that I can turn off the fog lights if I don't want them to come on, since otherwise they will always be on with the add-a-fuse.

If you have an auto there should be a clutch plate on the firewall where the clutch would go and you can go through that. If your like me with a manual i went through the grommet on the passenger side. If you drop the glovebox its quite easy to run wires through it.

So I got my fog lights installed and went to run the wires into the cabin and I can't seem to find a place to pull the wires thru the firewall and the a pillar doesn't look promising, any advise????
I'm running an H11 fog light wiring kit with Injet Ford Focus housings.

Now if you are asking about wiring in a switch INSTEAD of wiring in the relay - as MonkeyGrits said - that would POWER the fog lights off the parking lights circuit. It MIGHT work, but I don't think it's a good idea - you're risking best case blown fuses and worst case an electrical fire or fried BCM to avoid wiring in a $5 relay.
I know your BCM probably won't work with fogs as-is. But Chaddz3's Focus S BCM wouldn't either and he didn't even have the fuse for the fogs, but he DID have the wiring from the BCM to the front of the car.
First thing I would do is see if you have the C144 connector on the drivers side of the car near the fog light location and if you have the two brown wires that he mentions at Pins 18 and 19 of the BCM connector near the glove box.
Assuming you do - get Harness CV6Z15K867B - lists for $14.32. This goes to the fog lights from C144. It's not much more than buying the plugs from the autoparts store and you don't have any splices showing. Then personally, I would wire it up like Chad did - leaving out or hiding the switch if you wanted to.
The reasons I like this:

I understand what Chad did. I was just seeing if I could just use a switch (left to on) that would work in the similar place as the 2nd relay to the parking lights.
Either way, w/ my '13 SE, someone else tried seeing if the BCM would take adding fogs and it didn't. The BCM didn't want to accept a new program (apparently it's VIN specific and not really programmable). So, not sure what you're insinuating about the OEM harness. Are you suggesting I run the OEM harness to the relay?
Thanks again for all the info.

@MonkeyGrits - Yes. Shouldn't really need a fuse as the circuit is already fused.
@The Jordan - No. (Actually your way might work, but I'm not sure. It's not the voltage drop that would worry me - it's two things: I don't think there is a convenient low-current wire to tap off of for the signal for the headlights on switch. Also, the car sensing the wire to let you know when a headlight is burned out - not sure if it is sensing voltage or resistance or if it matters, but it might cause you to get a headlight out indication on the dash.
Chaddz3 explains what HE did in the other thread (and the post above the one I linked to):
What we are going to do is build a Fog Light Control Module Relay Box that will run the fog lights only when certain conditions are present. (Ie only when we want them to be on)...
Since our cars like to kick the parking lights on when we use the key fob to unlock the car, we can't just simply tap into the parking light wiring just by itself.. otherwise the foglights will light up when ever the parking lights do, Since i live in an apartment this would really piss off my neighbors. Plus it don't look very professional..
But also we just cant tap in to the ignition either or our fogs would be on when ever the key is on... (Don't want that either)...
By using two relays and feeding one relay off the ignition feed, and one of the parking lights feed, and having the fog lights driven directly off the battery, We have more control over when the fogs can come on. I wired mine so that both relays have to be active in order to have the fog lights active. The ignition relay is first in the line, followed by the parking lights relay. if either the ignition switch is off, or the parking lights/Headlights are off, the fog lights will be off too.
Second reason for the relay setup, is since every light in the car is driven off the BCM, there is a possibility that by driving the fog lights directly off the parking light circuit (without their own power source), it could overload the parking light circuit inside the BCM and possibly burn the traces for that circuit on the circuit board (which means you have to replace the BCM). Granted nothing may happen but since they want more than the GDP of some small African Nations to replace the damn thing, Driving them directly off the parking lights or any other BCM output is something i don't wanna try.
Overall, building the Control Module and tapping it in to the car's wiring is not really very difficult, but if you don't like dealing with wiring or unsure, i wouldn't try it. Since we are dealing with the body control module, it can be damaged if you aint careful.
All I Can say is this did work on my car with no ill side effects during testing. If you screw up your car, I'm not responsible..
14 Verify the fog lamps are functioning correctly in all operating modes
Key off - Fog lights off regardless of headlamp Switch Position.
Key On - HeadLights Off - Parking Lights Off - Fog Lamps Off
Key On - Headlights Off - Parking Lights On - Fog Lamps On
Key On - Headlights ON LowBeam - Parking Lights On - Fog Lamps On
Key On - HeadLights ON HighBeam - Parking Lights On - Fog Lamps On.
Key Off - Headlights Off - UnLock Car with Key Fob (or open car door with key off) - Park Lights On - Fog Lights Off.
Obviously, he put a lot of thought into this.
If you read through the other thread - Ford ran the wiring from the BCM to under the hood already - so you only need a $15 harness that Ford left out to connect the fogs. (At least on the 2012 Focus S - I would assume they did on the 2013 Focus SE - but who knows with Ford ...)
Now you can wire in two $5 relays inside the car to turn the fogs on.
I don't see any reason you couldn't do the wiring under the hood if you wanted to, but you would have to find a 12V ACC IGN source and a parking light circuit under the hood, and the factory wiring is already there and unused.
Differences between your circuit, his circuit, and the OEM circuit:
